生活垃圾焚烧行业二恶英的产生与控制方法

摘要

二恶英类污染物具有极强的生物毒性和环境稳定性，一直受到社会各界的广泛关注，生活垃圾焚烧行业是二恶英重点排放源之一。该文阐述了二恶英的理化性质、毒性特征及生成机理，对二恶英排放控制方法进行了比较和分析，得出了有效实现垃圾焚烧过程中二恶英减排控制的措施与建议。%Polychlorinated dibenzo-p-dioxin and dibenzofurans(PCDD/Fs)have attracted much attentions all over the world due to their seriously biological toxicity and nondegradation.The industry of domestic waste incineration is one of the main estimation sources.In this paper,the physichemical properties,toxicity characteristic and formation mechanism were amplified.Based on the comparison and analyzing of the domestic and overseas control methods,the effective measures for reducing the estimation of PCDD/Fs were suggested.
